- 1 Bar = 1.01972 Kgf/cm2
- 1 Bar ＝100kPa
- 1 bar = 14.5038 Psi
- 1psi=6.895KPa
- 1psi=0.070307 Kgf/cm2
- 1MPa = 1000kpa = 1000000Pa
- 1kpa = 0.145038 psi
- 1kpa = 0.0101972Kgf/cm2
- 1Kgf/cm2 = 98.0665 kpa
- 1Kgf/cm2 = 14.2233 psi .

mpa = megapascal
psi = Pounds per square inch
kpa = kilopascal of 1,000 newtons per square metre
Kgf/cm2 = Kilogram Force per Square Centimeter.
bar = metric unit of pressure defined as 100,000 Pa / 100kpa , 1 bar is roughly the atmospheric pressure on Earth at an altitude of 111 metres at 15 °C.
